jQuery CouchDB-筛选视图的键 [英] jQuery CouchDB - filter keys for view

问题描述

我正在使用沙发床附带的JavaScript库来查询数据库。

I am using the javascript library which comes bundled with couchdb to query the database.

在旁边的注释中，它很好地概述了其提供的功能，并提供了许多很好的示例。

可以通过指定要返回的键值从视图中过滤结果。使用查询字符串即可轻松完成此操作（文档），但是如何使用javascript API做到这一点？

It is possible to filter the results from a view by specifying the key values to return. This is easily done with a query string (documentation) but how do I do it with the javascript API?

这就是我使用查询字符串的方式（请注意，键值对的JSON部分需要进行HTML编码）：

This is how I am doing it with a query string (please note that the JSON portion of the key-value-pair would need to be HTML encoded):

http://localhost:5984/MyDocuments/_design/MyDesign/_view/MyView?key=["Michael","2011-08-01"]

这是我的javascript，其中未应用过滤过程的查询字符串部分。

And this is my javascript without the query string portion of the filtering process applied.

$.couch.db("MyDocuments").view("MyDesign/MyView", {
    success: function(data) {
        console.log(data);
    },
    error: function(status) {
        console.log(status);
    },
    reduce: false
});

推荐答案

我在写问题时实际上已经想到了这一点。相当简单，但在线上没有很多示例，因此需要利用这个机会来提供示例。

I actually figured this one out while writing the question. It was reasonably easy but there are not a lot of examples online so therefore feel the need to take this opportunity to provide an example.

$.couch.db("MyDocuments").view("MyDesign/MyView", {
    success: function(data) {
        console.log(data);
    },
    error: function(status) {
        console.log(status);
    },
    key: ['Michael','2011-08-02'],
    reduce: false
});

关键部分是您要查找的内容：）

The "key" section is what you are looking for :)
